Answers to common questions. If something doesn’t work, write to me.

Which audio formats can LigoVox read?

Anything macOS can play, such as MP3, M4A, M4B, AAC, WAV and AIFF. Existing M4B files are imported with their chapters.

Does the result work in Apple Books?

Yes. The M4B file includes chapters, cover art and book details and plays in Apple Books, most audiobook apps and on iPhone.

Are my files uploaded?

No. Joining and transcription run entirely on your Mac. See the privacy policy for details.

Why do I have to download a model for transcription?

Speech recognition needs a model of a few hundred megabytes. To keep the app small, you download it only when needed under Settings → Transcription. After that, transcription works offline too.

Can I keep working on a project later?

Yes. “Save” stores the file list, chapters and book details as an LigoVox project that you can open again later.
